I fucking hate my boss so much

He looks down on me like I’m some idiot who doesn’t know his shit.
The other day he was trying to explain OAuth2.0 to me in the most dumbed down way ever, even after telling him I do already know how OAuth 2.0 works. He just said “oh well just making sure” and continued explaining it to me the exact same way. Felt shitty having something explained to you which you already know in such a way in front of all of your coworkers

Whenever I give my thoughts on something he answers with an argument that’s essentially true but pretty stupid:

B: “We don’t need to bundle our JS files” (see my other rant)
M: “Our load time is around 15 seconds though and it takes forever to update our script tags”
B: “Yes but it’s only 15 seconds once and the tags are already there so it’s fine”

How do you reply to something like that??

On top of that, his code is absolutely awful, always looks hacked together, lacks documentation and i don’t think he has written a unit test in his life

I don’t even like frontend, was told I would mostly do backend and it seems like all I’m doing recently is write fucking javascript because even if I wanted to write backend code, it’s nearly impossible to write clean code in this pile of horseshit codebase
